Isometric ankle eversion and inversion were assessed in 3 different dynamometer foot-plate positions: 0\u00b0, 7\u00b0, and 14\u00b0 of inversion. Two maximal repetitions were performed at each angle. Both limbs were tested (40 ankles in total). The test was performed 2 times with a period of 7 d between the tests.<\/jats:p><\/jats:sec><jats:sec sec-type=\"setting\"><jats:title>Setting:<\/jats:title><jats:p>University hospital.<\/jats:p><\/jats:sec><jats:sec sec-type=\"participants\"><jats:title>Participants:<\/jats:title><jats:p>The study was carried out on 20 healthy athletes with no history of ankle sprains.<\/jats:p><\/jats:sec><jats:sec sec-type=\"main outcome measures\"><jats:title>Main Outcome Measures:<\/jats:title><jats:p>Reliability was assessed using intraclass correlation coefficient (ICC<jats:sub>2,1<\/jats:sub>); minimal detectable change (MDC) was calculated using a 95% confidence interval.

Eversion peak torque was the smallest when testing at the 0\u00b0 angle and gradually increased, reaching maximum values at 14\u00b0 angle. The increase of eversion peak torque was statistically significant at 7 \u00b0 and 14\u00b0 of inversion. Inversion peak torque showed an opposite pattern\u2014it was the smallest when measured at the 14\u00b0 angle and increased at the other 2 angles; statistically significant changes were seen only between measures taken at 0\u00b0 and 14\u00b0.<\/jats:p><\/jats:sec><jats:sec sec-type=\"conclusions\"><jats:title>Conclusions:<\/jats:title><jats:p>Isometric eversion and inversion testing using the Biodex 4 Pro system is a reliable method.
